Application: Designed for long-term storage of sheet film format negatives, transparencies and contact photographic prints. Use with Interleaving Folders for safe handling and protection from from dust and other pollutants. Store in archival boxes, either our Hinged Lid or Short Top boxes.

 Features: Constructed with double edge seams. This design ensures that envelopes stack perpendicular rather than in a fan shape, which can occur with conventional envelopes. Seams are bonded with pH-neutral adhesive. Outside seams provide a smooth inner surface. The open end has an 1/8 inch lip for easy access to contents. Constructed of heavyweight 7-point card stock, acid and lignin free, in cream color.

Note: Archival storage envelopes should not have center seams. Localized pressure on the seam will usually fall in the center of the contents and over time may cause damage.

Ordering Information: Price codes A,B,C apply to quantity breaks as shown. Envelope category orders are combined in cart and recalculated at checkout for lowest pricing level.
